IgorE350

Wow!!! i see you got a nice project on ur hands. Thank you for the pics,from ur pics i know where to look for the expansion valve and what to take out. Really appreciate that. Did you get urs fixed?

e reyes

I am waiting for some money to buy the parts the heat is umberable

IgorE350

Yeah i know, same here, i cant even drive my car its black with black interior its like a hot frying pan

Wanted to tell you something, i don't know if you did it or what year is your car, but i took my in car temperature sensor with aspirator blower its located by sunroof switch. that thing was full of dirt. Took brake cleaner and just 1 quick spray made it like new. So if you didn't check it yet, it would be a good time to do it.

Hi all, back with the update.
Installed the new compressor, new expansion valve, new drier. Pulled the vacume on the system to get all the moisture out and see if theres any leaks, everything looked good. Filled it up with new freon 2.5 lb for what it called even got a little digital weight to get the corrects amount in.

My ac is working so good now,WOW! I can make ice now

I spent about $400 on everything Got a good deal on ebay for New Denso compressor for $285 Valve was $30 drier was $30 and freon was around $50

MB dealer give me price on parts only $1100 never called me back on labor, i just can imagine how much the labor would be plus they told me to diagnose the problem would cost me $265

Wasn't that hard to replace it all, just take time, no rush and everything went smooth.

Thank you guys for all the help Now i can enjoy this Beauty!

open the old compressor and check the insides , reed valves, pistons, o rings ,clutch mechanism and speed sensor....

IgorE350

I threw thhe thing out, all i care that i have cold air. Did you get urs fixed yet?

e reyes

how much oil you put in the new compressor?

IgorE350

Didnt put any oil in there im almost positive that it came with oil. i just checked on Denso and it say that all there compressors come with oil. Maybe im wrong??? Did you get ur ac working yet?

e reyes

I fix the vaccum leaks . it blows cold like 50 degrees F. at the evaporator sensor with 14 bar high side pressure and clean the inside temp sensor on top of rear view mirror I got the expansion valve and receiver drier now evacuate the old Freon I am going to reseal the a/c compressor just to learn more ... how cold is yours like 39 degrees f ?

IgorE350

Was i right about the inside temperature sensor, was it filthy?
To be honest i didn't even check how cold it gets, but my wife been complaining that its freezing in the car so i didnt even bother to check. it gets really cold, i am very satisfied.
What did u mean by reseal the a/c compressor?
Was i right about new Denso compressor comes with oil already? im kinda worried now

e reyes

open the compressor and put new o rings shaft seals

Sounds like a project, Let me know how it come out for you sounds like you almost there.

IgorE350

Wow!!! looks like you had fun!! did you find anything that was wrong with the compressor?
How much time does it take to rebuild one and how much $$ for the new part for it? Just wandering if its worth to do it or just get a new one.

e reyes

50 dlls in parts 20 minutes to take it down

one day to clean the outside

2 hours to rebuild

and 40 minutes to put it back

the oil was brown

the new oil is clear like water

tomorrow or next week vaccum the syst

I add 4 oz of oil I fill it by the speed sensor......

when you do the vaccum the vacc. don't vaccum the new oil???

IgorE350

Not bad, but i wouldnt have time to do all that, the min i go to the garage pull out my tools she start calling me and bugging me when ill be done lol

No i dont think that vaccum pulls any oil out, pulls out moisture and air. i dont know how is that possible but it is

e reyes

and 40 drier

24 expansion valve

and 2.6 lbs of r134

fireman1073

my 94 did this and it was a wire on the compressor that indicates that its spinning before engaging the compressor clutch
the wire was intermittent so it would occasionally disengage
sometimes shutting the car and restarting would restore operation
check for a bad or broken speed sensor on the compressor

Steve

oops i missed the second page of posts ....disregard this post

IgorE350

Hey Steve wile i was doing the whole job i notice the same thing, green wire on the plug to the compressor was loose i just took the plug apart and solder it. Not sure if that was my problem but i fixed it.

IgorE350

E reyes, did you get ur ac going?
